Application led September 27, 1907. .Serial No. .394,836.

To all whom it may concern:

Be it known that I, MORRIS T.v LYNCH, Jr., a citizen ofthe United States, and a resident of the city of New York, borough of Brookl in the county of Kings and State of New lirk, have invented a new and Improved Collapsible Packing-Box, of which the following is a full, clear, and exact description.

The invention relates to paper boxes, and its object is to provide a new and improved collapsible pa er packing box, more es ecially designe to take the place of expensive wooden packing boxes, and which is simple and durable in construction, ca able of standing hard usage in ship ing an the like, and at the same time fu llyprotecting the contents of the box. f

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out 1n the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a erspective view of the outer shell of the box ody Fig. 2 is a similar view of the inner shell of the box body; Fig. 3 is a perspective view of one of the ends; Fig. 4 1s a erspective view of the 1m rovement, showing the parts assembled an the top or cover piece in position for finall closing or sealing the box; Fig. 5 is an en arged cross section of the improvement completely closed up, the section being on the line 5-5 of Fig. 4, and Fi 6 is a perspective view of one of the shells 1n a folded position.

The box body is formed of two open-ended shells A and B, preferably made rectangular in cross section, and of such'size that the shell B fits snugly into the outer shell A and extends throughout the height ofthe shell A, as lainly indlcated in Figs. 4 and 5. Each of t e shells A and B has its corners creased, to ermit of collapsing the shell diagonally, so t at two adjacent sides extend in the same plane and are superim osed by the other two sides lying in a para el plane, as shown in Fig. 6. This arrangement permits conveniently packing a large number of shells in a com aratively small s ace.

T e shells A and when assembled are securedI together by suitable means, such as staples or the like, preferably, however, by.

an adhesive substance C, placed in band] plete and inde endent rectan form around the outside ofthe shell B, at or near the middle thereof, so that when the shells A and B are assembled the adhesive substance C engages the inner surface of the outer shell A, thus nnly unitin the two assembled shells A and B with eac other.

The ends D and D for closing thebox body at the top and bottom are provided wit flaps D2, adapted. to be passed between the outer and inner shells A and B, at the end thereof, as plainly indicated in Figs. 4 and 5, the said flaps D2 being'provided at the inner faces with an adhesive substance E, for securely fastening the laps in osition .after they are passed between the s ells A and B at the ends thereof.

Now by the arrangement described, an exceedingly strong and durable box body is provided, as the two shells A and B it snugly -one in the other and thus reinforce eac other, to readil withstand rough usage in shipping the ed boxes from one lace to the other. `The shells A and B as we as the ends D and D arepreferably made from box board, so as to be sufliciently strong to read-v .tom iece D is laced and secured in position on tie box bo and then the box is lled, after which the top D is placed and fastened in position, so as to completely close and practically seal the box hermetically.

It will be noticed that any injury to the shell A is not liable to affect the contentsof thebox, as the same are then still protected lby the inner shell B.

Having thus described my invention, I claim as new and desire ,to secure by Letters Patent:

1. A paper box, consisting of two comlar shells of substantially t e saine lengt snugly one within the other, the shells being creased at the corners to permit them to collap'se diagonally and the inner shell having an adhesive substance on its several sides at about its center of length for securing it within the outer shell to form a box body with double walls throu hout its length, and ends for closing the bbx ody, said ends having inch the botand fitting tegral aps extending between the ends of the shells and having an adhesive substance thereon for securing them in position.

2. A paper box, comprising two complete and independent o en ended shells of substantially the same ength and fitting snugly one within the other, the shells being creased at their corners to permit them to collapse diagonally, means for securing the shells tom gather intermediate of their ends whereby to form a boxbody with double walls throughout its length, closures for the ends of the I said body, each closure having integral a s extending between the shells, and means fidi* securing the aps of the closures between the 15 said shells.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
